2 Thessalonians 1:5-9

All of this proves that God’s judgment is always perfect and is intended to make you worthy of inheriting the kingdom of God, which is why you are going through these troubles. It is right and just for God to trouble your troublers and give rest to the troubled, both to you and to us, at the unveiling of the Lord Jesus from heaven with his messengers of power within a flame of fire. He will bring perfect and full justice to those who don’t know God and on those who refuse to embrace the gospel of our Lord Jesus. They will suffer the penalty of eternal destruction, banished from the Lord’s presence and from the manifestation of his glorious power.
